Скачать или смотреть Unreal Engine Interact System Pro - New Update (Interact To Tag)

Tag-Based Interaction System
The tag-based interaction system allows you to define separate interactions for each Component (e.g. Mesh, Button, Panel) within a single Actor.

When this system is enabled (CanUseTag = true):

Interaction does not work at the Actor level, but is driven by the Tag on the hit Component.
Only Component Tags that start with the defined TagPrefix (e.g. btn_) are considered.
If no valid Tag is found:

Focus is not started
Focus end is not triggered
Interact is not executed
The old (Actor-based) interaction system does not act as a fallback
This allows:

Elevator buttons
Vehicle doors
Control panels
Multi-part interactive objects
to exist as a single Actor while each part produces different behaviors.

Summary: When CanUseTag is enabled, interaction is strictly tag-driven. If no Tag is present, the system intentionally produces no interaction.
